When the work begins to pile up And your temper starts to rile up That's the time a fellow needs a song Doctor, Banker, Butcher, Baker You can be a merry maker If you'll keep on singing all day long If you're hanging in suspense from eight till five And you want to keep the sense of humor alive Just, whistle while you work (whistle) Put on that grin and start right in To whistle loud and long Just hum a merry tune (hum) Just do your best Then take a rest and sing yourself a song When there's too much to do Don't let it bother you Forget your trouble, try to be just like a cheerful chick-a-dee And whistle while you work (whistle) Come on get smart Tune up and start To whistle while you work
